Hi Amber,
In your previous post (Stackexchange)  you mention that your test was made
on different plateform and you never test with CLI on the Android
plateform, so can't compare results obtained on a computer, and on a phone.
you would maybe try on your android palteform with another binary.

Regards,
WM
